I use recyclerveiw in my android app,
I use firebase-ui:2.1.0 in my gradle,but I find that if my android is 6.0 or over,
my app will bug.
So I update my dependencies to firebase-ui:3.1.0.
(refer to this link )
But It happened this error message:
How could I solve this problam? plz
I had the same problem.
Just make sure your
compile 'com.android.support:appcompat-v7:26.1.0'
version is the same as
targetSdkVersion 26
Mine was different and changing just this solved the problem.
i try to migrate minSDK from 9 to 14 (that's newest play_services minimum). Target SDK is 17. When i change it manually in gradle and manifest after sync, a huge list of problems showing up. Most of them has something in common with appcompact.
E:\Android\Android\android studio projects\Sklepik\app\build\intermediates\exploded-aar\com.android.support\appcompat-v7\24.0.0\res\values-v23\values-v23.xml
I think that these problems are because wrong version is in use (project works good few months ago), but i can't find place of declaration appcompact.
Right now i've got 2 dependiences in gradle:
dependencies {
compile 'com.android.support:support-v4:19.1.0'
compile 'com.google.android.gms:play-services:10.2.0'
}
How to solve it?
---> Keyur, after change support version i have problem which looks like:
of course my internet connection is ok...
Add support v7 library
compile 'com.android.support:support-v7:19.1.0'
Today, I update my Android studio to 2.3, and I update gradle to 3.4.1. But when I build my project, an error occurred:
This is the error
So I add " buildToolsVersion '25.0.0' "
My project can build successful, but another error occurred. I can't solve it. I hope to get some help. Thank you!
This is the error
When I add compile 'com.prolificinteractive:material-calendarview:1.4.2', this error will occur.
This is my androidDependencies
This is probably an issue with Android Studio 2.3. There's a new inspection that checks if all dependencies of com.android.support use the same version number. However, multidex doesn't have a matching version number. You can disable the inspection via the red light bulb icon next to it as a work-around for now
it's an unnecessary warning for the support:multidex, add this:
//noinspection AndroidLintGradleCompatible
compile 'com.android.support:multidex:1.0.1'
I'm also using updated Studio. You should use each library with the same version in order to avoid the Manifest Merger issue. Like this.
// To Support Design, CardView and RecyclerView Library
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:recyclerview-v7:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'
compile 'com.android.support:palette-v7:25.2.0'
// To Support MultiDex
compile 'com.android.support:multidex:1.0.1'
Here you will notice that each library have the same version.
Change version of com.android.support:recyclerview-v7 and com.android.support:support-core-utils to 25.2.0 (last version of support library: https://developer.android.com/topic/libraries/support-library/revisions.html)
Since today, Android Studio can't find the AppCompat themes in styles.xml, but for example AppCompatActivity in code does get recognized. My Android Studio version is 2.2.2, Build #AI-145.3360264
I already tried upgrading to the latest build tools, compile sdk (25) version etc. but it didn't fix the problem.
At the moment I have installed the following (from sdk manager):
android api: 19 and 23
sdk platform tools: 25.0.1
sdk tools: 25.2.3
build-tools: 23.0.2 and 25.0.1
support repository: 40
google repository: 39
and a few others, that shouldn't be necessary to list here.
build.gradle of app:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '25.0.1'
defaultConfig {
applicationId "xxx.xxxxxxxx.xxxxxxxxx" //not the real applicationId
minSdkVersion 14
targetSdkVersion 19
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('libs/RootTools.jar')
compile 'com.android.support:support-v4:23.+'
compile 'com.android.support:support-v13:23.+'
compile 'com.android.support:appcompat-v7:23.+'
compile 'com.android.support:design:23.+'
compile 'com.android.support:cardview-v7:23.+'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
compile 'de.hdodenhof:circleimageview:2.1.0'
}
Another solution that worked for me with Android Studio 3.1.2:
delete these from build.gradle if you have them:
'com.android.support:appcompat-v7:27.1.1'
'com.android.support:design:27.1.1'
then sync,
then undo delete,
then sync again.
I encountered this after updating to Android Studio 3.1.
None of the other answers listed here worked for me, however when I switched my appcompat support lib version to the latest 28.0.0-alpha1 then back to 27.1.0 that it was on before, it worked.
Seems the new version of Android Studio lost connection to where the library was synced to and just needed to have it reset.
No need to change anything.
Just press small button on top "Sync Project with Gradle Files"
EDIT: As #Alexey noted, bug still appears in Android Studio v3.1.4
This worked for me:
Click File > Close Project
Reopen the project from Studio's dialog.
That's because of feature called "build cache" that is enabled by default in build Android Plugin since 2.3.0.
It creates files in build cache outside of project folder (in my case -- in \Users\%username%\.android\build-cache)
Theese files are intended to be common between your projects.
And then Android Studio is unable to navigate in theese files.
That's all.
If you want to disable Build Cache, add android.enableBuildCache=false to gradle.properties file. Then restart Android Studio.
more info here:
https://developer.android.com/studio/build/build-cache.html#disable_build_cache
I have had the same problem. The only solution that worked for me was to manually delete the support libraries in file system and sync the project to let Android Studio download them again.
Steps:
Go to your project folder in File system
Go to .idea\libraries
Delete all the Gradle__com_android_support_****.xml files
Open Android Studio
Select File > Sync with File System
Once that is done, Select File > Sync Project with Gradle Files
Build Project
And now your error should be gone!!!
you can hit file -> invalidate Caches / Restart ... if it doesn't fix the issue you can close the project (file-> close project) and import it (file -> new -> import project.
I switched support lib to version 27.1.1 and problem has been solved. Seems like some bug in 27.1.0
I went through the same problem when I upgraded to alpha-2.
I looked at this link: http://tools.android.com/recent, but the only thing that worked well was:
Change this:
Classpath 'com.android.tools.build:gradle:2.3.0-alpha2'
For this:
Classpath 'com.android.tools.build:gradle:2.2.3'
In your build.gradle (Project)
Only this worked for me
Close project (File> Close Project)
Import / Re-Open project again (NOT from Recent)
Error should be resolved now.
If that fails, try below-
Open build.gradle, remove appcompact-v7 dependency and sync project.
Add appcompact-v7 dependency and sync.
I encountered same problem like this.Just the difference is I was using Studio 2.2.3. This is what solved my problem:
In my project level gradle I had:
classpath 'com.android.tools.build:gradle:2.3.0-alpha2' (which was a result of updating studio)
which I replaced with:
classpath 'com.android.tools.build:gradle:2.2.3'
I think you should look for a compatible classpath for your gradle configuration.
I was having the same issue after linking Firebase to my app. Updating the build.gradle in the app module did the trick, updated to:
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.google.firebase:firebase-database:11.8.0'
I had also the same problem when I upgraded my android studio from 2.2.2 to 2.3 Canary Version.
Although the new beta version of 2.3 is released yet it is using the gradle plugin of 2.2.3 which is of stable version.
So just change the classpath dependency in buildscript of build.gradle project level from alpha to 2.2.3 and sync it. It'll resolve the issue or change to the more appropriate version with respect to your channel version.

In newer versions of Android Studio, we are asked to use 'AppCompat'. Some users uncheck that and still use the Theme.AppCompat. That makes up this error. Same happened with me.
Solution is to add this line in your build.gradle (app).
compile 'com.android.support:appcompat-v7:26.1.0'
#Daniel Wilson made a comment in one of the answers that solved this issue for me. I wanted to add add as an answer to draw more attention to this solution.
Updating compileSdkVersion and targetSdkVersion from 26 to 27 (and then of course updating the dependencies) eliminated the errors for me.
Mine was fixed by deleting the .gradle file from the folder and re-importing the project in Android Studio
I also faced the problem with Android Studio 3.1 , syncing does not help me.
Then I switched back to
`'com.android.support:design:27.1.0'` from : `'com.android.support:design:27.1.1'`
and added android.enableBuildCache=false to gradle.properties to disable build cache
This is weird, I encounter this problem as below:
Android Studio is 3.1.2
support lib version is 27.0.0
I solve this by below:
change support lib version to 27.1.0, and "Sync Project with Gradle Files", then this error disappear
change support lib version to 27.0.0，and "Sync Project with Gradle Files", then this error not appear again
Deleted .idea and .gradle from project folder.
Then sync with gradle files, it worked.
I ran into the same problem when updating the Android Studio software.
What I did was this:
Go to the Gradle Settings as follows (this path is for Mac, but should be similar on Windows):
Android Studio -> Preferences -> Build, Execution, Deployment ->
Gradle.
Then pick "Use default gradle wrapper (recommended)".
If you already have that option chosen then your problem must lie somewhere else.
I changed my gradle version from
classpath 'com.android.tools.build:gradle:2.3.0'
to
classpath 'com.android.tools.build:gradle:2.2.3'
and it works now!
In Android Studio 3.1.3, the simple work around:
"Sync Project with Gradle Files"
If none of these methods mentioned by other contributors does not work for you..
Then please simply ignore this...
Even flutter officials also said to ignore these errors..
Caution*** Only ignore after trying all the methods.If above methods solve your errors then fine otherwise you can ignore these..
This type of errors happen after installing latest version of flutter sdk,gradle ,android studio and other plugins -packages
If you are using latest version then you have to ignore these errors.
After adding the appCompat v7 library I get the error that R cannot be resolved, which is apparently due to the fact that R now exists twice. I found an answer to that problem here : Build errors after adding fullscreen activity in Android Studio
However, I dont have or cant find the file attrs.xml in \src\main\res\values\attrs.xml. Is there any other solution to that problem or can someone give me a detailed description of how to do that in Android Studio?
Thank you very much!!!
Put this in your /app/build.gradle file :
dependencies {
compile 'com.android.support:support-v4:18.0.0'
compile 'com.android.support:appcompat-v7:18.0.0'
}
and make sure the version code (here 18.0.0) is not higher than the buildToolsVersion in the same file :
android {
compileSdkVersion 16
buildToolsVersion "18.0.0"
}
then rebuild your project. Hope that helps!
Oh and make sure you have the right buildTools installed via SDK Manager! Actual version is 21.0.2 I think.
I'm may be noob, but after several search i was able to add appcompat.v7 in android studio.
Initially i was comfortable with Eclipse after Dex Error 65535, my whole hard work was doomed i thought.
As Honey suggested you have to add both support.v4 or v13 and appcompat.v7 in build.gradle.
That's it. This simple solution not even covered in google docs ;). A simple reminder appcompat depends on v4 or v13.
